blueprint

[steady night]

whats the first thing that loads ?

my gameinstance ?

[remote meteor]

yeah

after all the module startup, the first thing that is game framework related is the game instance

for loading screen stuff

[steady night]

so if i were to use the "event init" in instance maybve it would load before ?

[remote meteor]

i recommend looking into CommonLoadingScreen plugin in Lyra

[steady night]

oh'

[remote meteor]

the moment you see the viewport, you should already have player controller though

[frosty heron]

Laura said just snatch it but I don't know how 😔

[remote meteor]

copy paste it to your plugin folder

[frosty heron]

Oh wow, that simple 👀

[steady night]

https://gyazo.com/3812e18db2ac8f51665708dfe127b359

well yeah this is the problem obviously

the loadingscreen istself works fine i just need it to pop up faster idnno if thats possible:

[remote meteor]

when are you adding it now?

[steady night]

controller

[remote meteor]

begin play of controller?

[steady night]

hmm wait im acctualy doing it in my HUD

[remote meteor]

begin play of hud is also fine

[steady night]

aye its there but still to slow

[remote meteor]

standalone or?

[steady night]

no its for the clients

same for standalone

acctualy

[remote meteor]

probably need to add it while the map is already loading

that means, use the plugin 😄

[main lake]

I created a component and added it to my player and I'm seeing that components have 2 events "On Component Activated" and "On Component Deactivated". Are these events called when the component gets attached to the player or only when I add it to the player before runtime and it runs when it's starting runtime (being like "Begin Play" but for component) ?

[thorny forge]

Hey guys can you tell me if this is stupid or not please?

I'm trying to get rid of this:

[remote meteor]

they run before the component's begin play

[remote meteor]

you sure you looking at the right place? i dont see the Baby property

[main lake]

But do they run once I add that component to the player dynamically during runtime ?

[thorny forge]

Yea sorry it's a bit further down

[delicate anchor]

Hi.
Iam Recreating The Blue Spheres Special Stage From Sonic 3 And Knuckles.
But In The Original Game When There Are Red Spheres In The Outer Formation (Red Spheres Forming a Square Of 9 Spheres Or More Can Work With Anything In The Middle Of The Square)
All Of The Spheres Turns Into Coins (Rings In The Original Game)
But I Can Not Find Anybody Done The Same In Any Tutorial
I Had The Idea To Make A Formation Of Blue Spheres In A Blueprint
And But Collision Boxes On The Outer Spheres Of The Formation
But I Want This To Be More Flexable In the Level Design Because The Original Game Had More Tha Only Square Formations And A Want To Put A Level Design Mode In The Game So That If AnyBody Made A Square Formation Of Individual Spheres It Will Function Like The Original Game
So Please If Any Body Can Help Me With My Problem

[remote meteor]

yeah?

on registering of the actor component to the actor, they will be called

assuming the actorcomponent has auto activate enabled

[main lake]

Thx

[remote meteor]

else you would need to activate it yourself

[main lake]

where is that ?

got it

thx

[main lake]

so that means if it has "Auto Activate" then it will call Begin Play, and if it doesn't have "Auto Activate" it won't call "Begin Play" until I activate it, right ?

[thorny forge]

Can you tell me if what I've done here says "If any of these are valid, then activate the skeleton, if any are not valid, then continue onto 'bind event to On Finished'

[cobalt gulch]

Is there a way to do this while falling in mid air? It seems to slow the character down temporarily when changing the gravity scale where as i'd like it to speed up from the current speed

[remote meteor]

its more like "For each BP_Niagara, if its valid, activate skeleton. Binds event anyhow"

[delicate anchor]

this is the Blue sphere BP that i made

@delicate anchor

[thorny forge]

If I were you, I would just make it so 'If blue sphere collisions are hit consecutively then turn all into rings'

The original game made it so that even if you hit 6 our of 9 but you had to miss one (meaning there's more than 1 second delay between hitting another sphere) then they don't turn into rings

[thorny forge]

So I'm basically telling it to activate the skeleton for whichever BP_niagara is valid, but bind the event regardless?

[remote meteor]

yes

[thorny forge]

Ok, I'm new to this still so trying my best to understand lol thank you

[delicate anchor]

and Here is the red sphere spawner BP (and yes i made anothe BP to spawn the red sphere because i hade some problems)

and here is the red sphere

[thorny forge]

Did you read what I suggested above?

[delicate anchor]

sorry but i did not get what you said iam still scratching the surface of this engine and it crashed just right now

[thorny forge]

I understand. So you're trying to get the rings to replace all the blue/red spheres if the player hits a number of spheres in the right order right?

[delicate anchor]

yes if the player turns all the blue spheres in the outer perimeter of the formation

i will show some gameplay now please wait my pc is from 2024 B.C.

it crashed again

[thorny forge]

Ok, So in the original game, even if the player hits all the spheres on the outer perimeter but leaves the spheres, turns around and comes back to finish the rest they don't change into rings

so you need something like a timer or a delay per sphere overlap that resets the event which will turn them all into rings if the delay has change to finish, but if the player overlaps another one the event is reset

[delicate anchor]

no if the player just turned the outer perimeter of the formantion into red spheres all of the spheres inside and outside blue and red turns into rings

[thorny forge]

yea I know that

but only if the player is running over them conitnuously

continuously*

of the player leaves the square and then returns, it doesn't change them to rings

try it yourself

[delicate anchor]

no all of the square like in this gameplay turns into rings

[thorny forge]

Anyway to get them to all change into rings, you need to make the spheres on the outer perimeter have a tag, so you can call it for each time you overlap one. The inside ones wont have a tag, then you can say:

"For each one overlapped within 0.5 seconds since the last one, and 6 has been overlapped and turned red. Turn all spheres in this grid into rings"

[coarse grove]

Hello guys, im actually trying to do an area damage around the player. Its made from some explosions but I want to control exactly the distance from player each explosion will spawn. What would be the best approach to do it?
I was thinking to get forward vector and multiply by a distance, then rotate it around player. Actually I tried to use the node "rotate around axis" but it did not work, they just dissapear. If I dont use the node, they spawn in a line, like the following image. Any Idea how could I solve this problem? Or there is a better way to spread them around the player?

[twin shale]

Code layout question: I have items that have loads of different actions that can occur (equip, equip to multiple slots, add to hotbar, etc etc). Right now I have actor components on the Pawn that read the items and perform whatever relevant process the item needs. For example I have a EquipmentManager component that just reads the equipped items manages changing and updating Skeletal Meshes. I was thinking about making the Item objects responsible for their own actions. I'm not sure if this is the best approach or not and I'm trying to decide how to proceed. Kinda just looking to see what other folks are doing

[delicate anchor]

sorry for missunderstanding but you can actually leave the square if you turned some of the spheres in the outer perimeter into red spheres and come to it again and complete the rest in the outer perimeter and this function will also work

[thorny forge]

Really? I swear this never worked for me. Fair enough, if that's the case then this will make it easier for you

Just have the ones on the outer have a tag called "outerSphere" or something

[delicate anchor]

how

[thorny forge]

And then just have a check that asks "if 6 with tag "outerSphere" have been turned blue then turn all objects in actor into rings instead"

maybe I'm wrong because there's a lot of ways to approach this

[thorny forge]

You can set tags like this

each component within an actor will have a component tag that you can create and name

otherwise the actor itself will just have a regular tag

[delicate anchor]

note: every blue sphere is a different actor from the same blueprint (BlueSphereBP)

here is the gameplay from the engine (sorry iam noob at my own game) this is what i mean now i want when i do this all of the spheres turn into rings

@thorny forge But in my case the coins that were shown in the gameplay (BlueCoinsBP) instead of the rings

@thorny forge If you want my project to test it out yourself just let me know

[thorny forge]

Let me have a think

Destroying and spawning actors is quite expensive in this case, I'm trying to think of a better way

[delicate anchor]

ok

[thorny forge]

I'm still thinking

[delicate anchor]

thank you and iam waiting with bated breath

[trim matrix]

How can I make the player focus on something? For example, let's say a TV is playing, and it's playing something important. How do I make it so if they try to look away, the camera slowly looks at the TV again?

[frosty heron]

Set Control rotation

interpolate from current to Target , target being the TV

[trim matrix]

Okay thanks. Would it be better to disable movement or should the player still be able to move around, just focus on the TV?

[frosty heron]

up to you

your game, your design

[trim matrix]

Yeah true

[astral geode]

Hi does someone know why the camera doesn't see the sky (i use "good sky" for my sky box)

[thorny forge]

Just testing

[delicate anchor]

alright

[main lake]

Somehow "Begin Play" of the component on my BP_Character is getting called when I press play even if I have "Auto Activate" set to false, so I'm kinda confused 🤔

[thorny forge]

Nearly there man and I'll show you how it's set up

[delicate anchor]

nice

[frosty heron]

@trim matrix Freebie

[vestal sapphire]

How can I create a category for actors? Or groups, or tags, or something?
For example, I have different weapon types: knives, guns, granades. Each has multiple actors in them for different weapons. How can I do a check inside of blueprint code that this actor is a grenade type, or this actor is a knife? I can't do this with a "class" check, because each individual is it's own bp class...

[frosty heron]

@trim matrix If you want to change the speed, just change the interp speed

[thorny forge]

Almost got it give me 1 sec

[delicate anchor]

you got it

[frosty heron]

You should have a base class for the weapons

and make child for each weapon type

[main lake]

Enums I guess

[frosty heron]

Make a base class for the weapon, each weapon (guns, grenade, etc) is derived from that weapon classs.
if you have an array of Weapon ref, you can just cast to check the type

or do equal check with the class, depending what you need

[vestal sapphire]

hm. equals check doesn't return true if the parent class matches, as far as I've tried.

[thorny forge]

Got the first bit for you 1 sec

[frosty heron]

it will, how do you check it?

[undone bluff]

nier ost spotted

[delicate anchor]

ok

[frosty heron]

best game to ever exist

[vestal sapphire]

Here, I made a child of a throwing knife, and recolored it. When I pick it up it checks if the class of the picked up object is equal to it's parent. And it returns false, sadly

[frosty heron]

Well cuz u are checking againts the parent

not the class it self

[thorny forge]

check your direct messages

[vestal sapphire]

But that's my point. I want to have something to check against, that will work for all the children. Or items in the group. Or whatever.

So if I have 10 different throwing knives, each as their own actor, I can have something to check that they are all of one type: throwing

[frosty heron]

You can cast it to the base class

though I don't have your project, I smell something wrong with how you structure your classes

but in any case

if u have an array of things, and u want to check if they derived from a weapon class

you can just cast the ref to the weapon base class

EG. BP_Weapon (Parent), child of it are (BP_Knife), BP_Grenade , BP_Sword

now there are an array

BP_Something, BP_Knife, BP_Sword

you can do a check with cast to see if they are derived from the weapon class

For Loop -> Cast the ref to a weapon class, if it's valid then it's a weapon class type

BP_Something will end up with cast failed while the rest will return succsess

[vestal sapphire]

Ah, ok

so like this, this works

[frosty heron]

No need to check for class here

get rid of get Class

Just get the blue pin -> Cast To Bp_Parent

especially if u need to access the instance. You better off casting the instance right away

[vestal sapphire]

Ok, that works too, thanks

[white field]

does a variable need to be public in order for a child to be able to alter it?

[frosty heron]

either public or protected

but in bp there is only public and private anyway

[white field]

hmm, I see

[frosty heron]

private will make the variable accessable to that class only, not even it's children

[white field]

what about something like Initial Speed within ProjectileMovement component?

[frosty heron]

@white field what about it?

[white field]

well that's like a variable within the component (not sure if that's technically correct way to describe it) and if the component is in the parent, say you wanted to alter it on children..

[frosty heron]

It's public variable

you can alter it

wether you should or not, i don't know

[white field]

heh

[hallow scroll]

hey guys I want to achieve a first person camera and I have a problem with my weapon actor that wont pitch automatically, so i have to set the rotation of camera from the player to the weapon actor (child component of the player)... but when i do this i can pitch BUT its stuttering when i do... any ideas? ... If u have any and ur done with your current thread, would be awesome 🙂

[white field]

ok thanks 🙂

[tight pollen]

I have no idea why, but in AI_Character I can't spawn Sphere Trace By objects, line traces, etc.

someone can help

?

[frosty heron]

Show code

[tight pollen]

@frosty heron

Animation is play

but Sphere Trace not

[frosty heron]

have u print string, make sure the sphere trace function gets called

[tight pollen]

is called

in Editor

in package game not

but animation is playing

[frosty heron]

Not sure how the top and bottom relates

but I never have a case where things don't work in package but works in editor

not saying that's not the case but I don't know what happend on your end

[tight pollen]

Attack Player is first

then is sphere trace

this is all

[frosty heron]

What u are saying is, u can't see the debug trace in packaged?

I would guess the debug draw mode is disabled on shipping but not 100% sure

[tight pollen]

sphere trace is not visible at all when I enter the Show collision command, but all others are visible

[remote meteor]

trace =/= collision 😅

[tight pollen]

ok

right

what can I do with this

how can I fix it?

where is issue?

[undone bluff]

late but I think you're looking for Is Child Of

[golden pagoda]

Hello, anyone know, how to make this type of menu , how much vram is remaining ?

[undone bluff]

there is no issue it's working as intended. You need to actively tell the trace to draw debug for it to be visible

[tight pollen]

how? where?

is set For Duration

and not Draw in a packed game

in Editor all is fine

collision works in Editor with this trace

but not in packed game

[undone bluff]

yea it's not supposed to, it's a debug visualization

what you can do is project the world position of the start and end of the trace to the screen

and then use that to draw a line in HUD

[hallow scroll]

Hey Guys! I Have the following Problem:

• When I set the transform of my WeaponActor to the position i get a weird stuttering only on pitch...It seems like it tries to set the location but steps back every tick and then it resets it...

Is there any different way to do this?
I Also tried to set a camera directly into the WeaponActor but then i cant pitch up and down...only left and right :/

[lyric quiver]

does event construct on a user widget get called every time the widget is created after being removed or only the first time?

[frosty heron]

you can hover over it and read the tool tip

it can get called multiple times, under some circumstances

it also tells u what you need to use if u only need a one time thing that runs when created.
OnInitialized

[lyric quiver]

I wasn't sure of the terminology here

[frosty heron]

well if u are not doing slate (c++) probably don't have to worry about it

[lyric quiver]

ok thx

If I have a variable in a user widget, change it's value during gameplay, and then delete the user widget, will the variable still hold it's changed value if I create the widget again?

[frosty heron]

Lets talk about delete first

how do u define delete

remove from parent doesn't delete the instance of the widget

[lyric quiver]

wrong word lol

[frosty heron]

Ok that doesn't delete the widget

So it's still hold the value (since the instance still exist)

and if u want to see the widget again, you can just add to viewport again

To delete widget, you need to remove from parent then set any reference to it to none. It will eventually get garbage collected

[lyric quiver]

Yh I'm just trying to debug why a bool isn't working as I want it to so was just making sure that wasn't the problem

[olive yarrow]

Willing to exchange pet pics for help 😦

[frosty heron]

Have an array to contain your items

add one everytime you pick something up

[olive yarrow]

Bless, i had tried that using a "for each loop" but it kinda messed up the rest of my system - is there a better alternative/maybe i did not put it in the right spot?

[frosty heron]

You can't possibly have inventory system without array

unless ur character can only have one item at a time

[heavy lynx]

Hello everyone, is anyone available to help with some issues regarding Delta Seconds math ? (I need help using the Event Tick for fake physics along a spline)
(hopefully this is the right channel)

[frosty heron]

I don't know what you use for each loop for

logic should be , on item picked up, Get the Item array -> Add the item to the array

[olive yarrow]

oh, i just used it for its array

[frosty heron]

Delta second is the time it takes between last frame and current frame

[heavy lynx]

Yes I do know that, but I am experiencing issues implementing it in my BP

[frosty heron]

probably best to figure out the math on paper then try to do it in unreal

if u need to set an object location, it seems like InterpTo is what you are looking for

[olive yarrow]

my bpc inventory is already a string array, i attempted a validated get for it in between pick up and add - but uh... i'm only able to pick up one item in general now so i may have made a booboo

[frosty heron]

a string 0o?

use a struct that contains all the data an item need

[olive yarrow]

i think that is also my bpc inventory.. it all kinda goes back there - i believe. my knowledge in unreal is only 6 months in

update - made the valid get after my second branch go into its branch for both is valid and is not valid. so now i can pick up both! buuuut it still over writes

[chilly plover]

Guys I am having an issue. I have a box collision with this BP overlap and a custom InputAction called: Interact assigned to the E key. But it doesn't work. Anyone have any ideas?

[frosty heron]

Where is this bp?

[frosty heron]

What gets overwrite? show the actual variable

[chilly plover]

This is a door BP

[olive yarrow]

oh, sorry - in game, if i pick up one item and then another my in game inventory will overwrite whatever was first picked up

[frosty heron]

That's the issue, your player doesn;t own the door. Any input called there will not work unless you set some setting which is a super terrible practice

Handle input in your player character

do the logic to interact there

[olive yarrow]

facts

[chilly plover]

This is for opening a door

[frosty heron]

yes

don't do any input anywhere that is not owned by the player

you either do it in your character or your player controller

[chilly plover]

How do I do that then as each BP has different door settings

[olive yarrow]

It's confusing at first, but you'll be CALLING the interaction from your player in the end for all interactive items

[frosty heron]

You normally want to use interface for interaction

[olive yarrow]

here's a peak at mine for instance, it's in my player bp

[frosty heron]

You are creating a new widget everytime u picking an item

is this intended? because it's really fishy from my perspective

im just another newbie tho

[olive yarrow]

no it definitely isn't intended haha
I'd like just one widget

[frosty heron]

if it's valid then dont create the new widget, connect the pin straight to the add item logic

[olive yarrow]

and here is TECHNICALLY my door. it's an interactive person, but the idealogy behing those two very different things (a person and a door) are essentially the same

[olive yarrow]

like so?

oh wait

[frosty heron]

No 😄

you still need the create widget

[chilly plover]

I need the BP in a datatable?

[olive yarrow]

lmfao thank you xD

Got it workin', now just gotta fix my ui 'cause that is noooooot how my vertical box is spose to be working

[olive yarrow]

?

[frosty heron]

I don't see how data table come into play for opening a door or interaction system

this is a data table

Interaction systems are widely covered in youtube pretty sure. A lot of them probably quiet bad but at least it's a start

[olive yarrow]

think of it like that, your door is going to have an event that calls to make sure the interaction from your player is successful. If they agree with each other, your door will more or less use that interaction from your character - and THEN in your DOOR you'll have that whole "rotate" blah blah

[frosty heron]

Depending on your game, you want to define how to initiate the door.
Seeing that you are using volume, Im just gonna assumed you are doing Top down or some sort

1. Player press Interact -> Get All overlapping actors
2. For each Loop -> Get Actor -> Implements interact? if true, call the interact (interface) then break

[olive yarrow]

[celest trench]

Hey everyone! How do I add an actor tag via blueprint? Also does the Player StartTag count as an actor tag if I were to use "Get all actors with tag"?

[carmine scaffold]

how would i make my movement input dir rotate with the ground normal so the controls will adapt when running on walls and upside down so the camera doesn't have to follow behind

Something like this
https://youtube.com/clip/UgkxDO3Q3kBc3OmkMzFO6kolU1f60WtfeJW0?si=8Awu8g3eYt2QV88I

im currently using ninja character

[broken wadi]

Player Start Tag is a different tagging system as is the Gameplay Tags. For actor tags you can click the + symbol beside the trashcan in your screenshot.

[celest trench]

I was just sending that to show the exact tags I meant. I am asking if there is a node in blueprint to add them dynamically

Thanks for the info about the start tag!

[broken wadi]

Tags is an array inside of actor. You can use add them using the Add Unique node with blueprints yes.

[celest trench]

Okay I see that. Thank you so much!

[steady night]

is there any way to get UI button "on button down" event ?

[edgy ingot]

U already have on pressed

[marble yew]

how to make temporarily nodes inactive ? i do not want to compile them yet

[steady night]

@edgy ingotyeah but that only fires once i want it repeatedly fiering

i can do my own logic ofc im just checking if theres a done way already

[edgy ingot]

Not that i am aware off

[steady night]

Yeah solved it

[turbid pecan]

Wanna validate something with yall. So I am doing my dungeon crawler grid movement bp on a FP template project.
I got the rotation down, so I can turn the camera 90 deg or -90 deg at a time. The thing is, the WASD movement seems to only be taking me in one direction no matter my orientation, which I assume is normal since I haven't done anything with it.

Am I correct in assuming that to get to my goal, I have to base my movement on the yaw of my actor? So for example say I start the game, yaw is 0 (my camera faces the X axis) therefore my movement calculations should apply such that W and S set actor location on X and A and D set it on Y, but if I rotate 90 deg, then W and S should flip to Y axis and A and D to X axis?

Or is there a simpler way?

[fluid lagoon]

Does adding components to the hands in the VR template stop controller tracking because this suddenly happened to my project today even though I havent touched the VR pawn settings, only added a collision box

[wraith basin]

Hello, I’m trying to make a movement system in UE5 where if I hold RMB and move the mouse, both the camera and my character's direction are affected, but if I hold the LMB, only the camera moves.

I enabled “Show Mouse Cursor” in my player controller and used “Set Input Mode Game and UI” inside my ThirdPersonGameMode to make it to where I had my mouse cursor showing unless I clicked, which would then hide the cursor and allow me to steer my camera and character, but the problem is that both the left and right mouse button do the same thing.

Here's a couple of examples. Left is how it's currently working, right is how I'd like it to work. Any help is appreciated

[undone bluff]

unless I'm misunderstanding you, you just want to enable "use controller rotation yaw" while RMB is held down

[faint pasture]

yup

mouse always changes control rotation

camera always follows control rotation

when rmb is down, character does too, otherwise it follows velocity

[turbid pecan]

hmmmm I think I moved a bit further in my quest.. So I think I figured out that I can use "forward" vector to dictate movement based on camera rotation.. however I am still not there

Can't quite grok how that plays into the movement calcs

[faint pasture]

Describe your desired rules

you want character orientation to be xxxxxxxxxx when xxxxxxx and yyyyyyyyy when yyyyyyyyyyy

[turbid pecan]

Are you asking me or Occams?

[faint pasture]

whoops wrong guy

[faint pasture]

You want to store either just the yaw value or a rotation

then rotate your inputs by that rotation to convert from WASD space to world space

[turbid pecan]

well I have rotation stored as a variable every time I rotate.

But I have no godly clue how to translate it

lemme post a pic of the current tragedy

[faint pasture]

rotate vector

make a vector out of your inputs

rotate it by the stored rotation (or by the camera rotation, which is typical for a game with camera able to be at any rotation)

bam, thats your inputs in world space

[turbid pecan]

This one isn't working at all how it should..

[undone bluff]

if you want to turn by 90 degrees to the right you just get your control rotation, then get its right vector and make that your new control rotation

interpolate to make it smooth

[turbid pecan]

I got the rotation down just fine already

[faint pasture]

Break that up

[turbid pecan]

im trying to make WASD work based on the rotation now

[faint pasture]

OK first off, what inputs do you have

do you have WASD as a vector?

or do you have MoveForward and MoveRight as separate axes

[undone bluff]

you add movement input, for W and S you get the forward vector, for A and D you get right vector

[faint pasture]

ok so you have a vector

[wraith basin]

So as of now, whenever I hold either the left or right mouse button, my character turns to follow the direction my camera is facing, but only while moving. This is only intended for the RMB. If I hold either button and rotate the camera without moving, the character stands still, which is intended for both. Currently, Use Controller Rotation Yaw is unchecked

[faint pasture]

@turbid pecanPrint that, make sure it seems correct

X should go 1 to -1 on W and S, Y should do the same on A and D

[turbid pecan]

On W press

I wonder if my EIA keys are set up with the right modifiers

[undone bluff]

are you trying to avoid using the character movement component?

even if so you should probably copy that setup for movement

add movement input will move the actor each frame and scale it by the deltatime

[turbid pecan]

im just using the FP template and I went into the event graph where it had the look and move stuff, and just disabled those and added my own mess

The thing is my movement needs to be precise, 300 units on any axis and only if theres nothing in the way on that axis

[lunar sleet]

Clamp

[turbid pecan]

I kinda feel like we are talking about slightly diff things now

Atm the only issue I have is that my WASD is not respecting the camera look

[faint pasture]

They sure aren't

[turbid pecan]

So say I am looking at the positive side of the X axis, I would like W to add 300 to x and S to subtract 300 from x

but if i turn 90 deg right, then it would be +300 - 300 on the Y axis by pressing W/S

[turbid pecan]

Yeah I had a suspicion. I don't really know how to do this yet... I dont even know what swizzle does.. Sadly

I just fudged it

[faint pasture]

Get WASD to output
W = 1,0,0
A = 0,-1,0
S = -1,0,0
D = 0,1,0

Swizzle moves from X to Y and from Y to Z etc

so w = nothing
A = negate swizzle
S = negate
D = swizzle

Once you get your inputs straightened out, then worry about the translation to world space

[turbid pecan]

ok done

Correct nums showing

So first off, thanks for helping here

[faint pasture]

k so set up your movement to totally ignore camera for now, just moves in world coords based on input

Input -> ??? -> Move in X direction

Rather

Input -> MoveDirection = InputVector -> do the move

Then once that's working, you can get MoveDirection to adapt based on camera

[deft prism]

Hey all. I'm having difficulty getting animation notifies to work. Inside my Animation Sequence called punch I added a skeleton notify called PunchEnd.
In my Animation BP I am able to right click and add the event. When the punch is triggered, the animation plays but the notify is never called. The punch animation is called from a state machine if that makes a difference.
Any thoughts on why the notify is never triggered in the AnimBP?

[faint pasture]

CameraRotation -> break -> yaw -> divide by 90 -> round -> multiply by 90 -> make rot -> this is now your rotation you care about

MoveDirection = RotateVector(RawInputVector, RotationYouCareAbout)

done

Assuming you already don't have a snapped yaw angle, if you do you can skip all that and just use it.

[turbid pecan]

OK so this moves properly atm when I start the game. I am facing +X and W moves me fwd, S moves back and so on:

[faint pasture]

set an intermediate MoveDirection variable

between the input vector and the do once

[undone bluff]

So as of now, whenever I hold either the left or right mouse button, my character turns to follow the direction my camera is facing, but only while moving. This is only intended for the RMB.
probably because Orient Rotation to Movement or Use Controller Desired Rotation is enabled in the movement component (probably the latter)
If I hold either button and rotate the camera without moving, the character stands still, which is intended for both. Currently, Use Controller Rotation Yaw is unchecked
if you don't want Use Controller Rotation Yaw to affect your character when it's not moving you just check if the velocity is bigger than zero while the RMB is held down and if not you turn it off

[turbid pecan]

Like so?

@faint pasture the rotation code I have is this:

It both sets the control rot by 90 or -90 based on Q or E press and also stores it for other uses

[faint pasture]

You should have a TargetYaw float variable and use that

The reason you'd want to do that is for precision

what if you move AS the camera is rotating

you'd move off the grid

So set a TargetYaw float there, which is only ever some multiple of 90, then you can use it in the movement side of things

just after the do once:
TargetYaw = TargetYaw + InputValue * 90

then use that in the movement code.
MovementDirection = RotateVector(RawInput, MakeRotation(TargetYaw,0,0))

[wraith basin]

I currently have Orient Rotation to Movement checked and Use Controller Desired Rotation unchecked. Whenever I uncheck Orient Rotation to Movement my character no longer turns to face the cameras direction, but still moves in that direction. I'm posting a picture of my IMC and Blueprints to see if that helps clear anything up.

if you don't want Use Controller Rotation Yaw to affect your character when it's not moving you just check if the velocity is bigger than zero while the RMB is held down and if not you turn it off

I unfortunately don't understand this. I'm brand new to basically everything.

Only real change I've made is to my Game Mode, where I added the control for hiding and revealing the mouse cursor

[faint pasture]

yes, because you're driving your movement direction by Control Rotation

what do you WANT to drive your movement direction by?

[undone bluff]

can you give a very simplistic point by point summary of the behaviour you want?

[faint pasture]

Probably wants to use the capsule rotation instead of control rotation for determining the movement orientation

that's really the only other possibility

[wraith basin]

While holding the LMB, I want WASD to control to direction of the player, while mouse controls the camera to swing freely around the player without affecting movement

[faint pasture]

that has nothign to do with movement like you were just talking about

or rather

direction of player and direction of movement are separate right now

do you want WASD to ALWAYS input movement relateive to the pawn's rotation?

[boreal crypt]

Has anyone dealt with crosshairs for third person games?

My character is offset from middle, and I'm using a projectile that comes from a point on the mesh, out towards the direction the camera is looking.

When I try to adjust the crosshair position, it is always off in some way. Either it lines up perfectly when hitting something up close, but then it is off when hitting something far away, or vice-versa.

If I do a line trace from the fire point in the direction and then ProjectWorldLocationToWidgetPosition from the impact point, it works, but the crosshair also jumps around wildly.

I don't think I've ever played a 3rd person game where the crossthhair didn't align with where e projectile/shot would go, and it never really jumped around wildly.

Video of issue:
https://gyazo.com/5e460054797e8f636c38a13a4ac7482a

Attached is my blueprint for my projectile transforms, I've tried a variety of values for how far out from the camera to "aim", 50, 5000, doesn't seem to make a huge difference.

I'm wondering if I need to line trace to that point on the screen, and then use the impact point there as the target in my find look at rotation?

[faint pasture]

Just use the capsule's rotation instead of control rotation in your movement input logic

[faint pasture]

That's a fundamental problem with 3rd person games

[undone bluff]

so while LMB is down you want to Orient Rotation to Movement, and not use controller rotation yaw

[faint pasture]

Do a line trace, and enforce some minimum and maximum aim distance you care about

[faint pasture]

You still want the mouse to move the camera at all times

[turbid pecan]

ok apologies if im being dense here...

1. Create a new variable called TargetYaw
2. Set it to something like 90?
3. On rotate input add "action value" * 90 to it?
4. Store the result as new TargetYaw?

[faint pasture]

just control rotation does/doesn't drive capsule rotation

[undone bluff]

ah fair point silly oversight

not use controller rotation yaw

[faint pasture]

Have TargetYaw ALWAYS represent the yaw the camera wants to have.
Use it as the yaw for movement transformation

RotateCamera -> update TargetYaw -> do the rotation
Movement -> rotate InputVector by TargetYaw -> do the movement

That way if you move halfway during a camera rotation you don't walk off the grid lol

you do want to move on a grid right?

[faint pasture]

You can avoid the DoOnce nodes by not using Triggered and using Started instead

it'll fire once per key down

[undone bluff]

I'm way too tired to be giving programming advice haha

[turbid pecan]

No I get that, I was just wondering what was wrong with the way I am doing rotation atm. Like the input from Q and E is either 1 or -1, which when multiplied by 90 becomes -90 or 90, but just a float. It's never different. The character rotation I get there always starts at 0. Because this is the default orientation.

To be clear - I am asking all these questions because I am also learning here. Not just doing stuff. I kinda wanna understand what I am doing and why

[boreal crypt]

@faint pasture thank you. I think I was making it more complicated then it needed to be... doing a line trace from the fire point to a point along the forward vector of the camera does seem to fix the issue, and it properly hits the crosshair point both near and far. I swear I did this before and it didn't line up, but so far so good

[undone bluff]

if they want to make holding a directional key down move repeatedly in that direction then I honestly am not sure how you could make this setup any better

even though I really don't like it

[wraith basin]

So this is what I was able to setup, not sure if it's correct, but it's has basically reversed the problem. Now, neither mouse button will control the characters direction.

So if the RMB was working correctly before, the LMB is working correctly now

[wraith basin]

I always want W and S to move forward and backward, and A and D to strafe left and right. While moving forward holding W, I'd like to be able to steer by holding the RMB. Alternatively, I'd like to be able to look around without affecting my characters direction while holding LMB. Does that clear anything up?

[turbid pecan]

@faint pasture

It finally clicked

phew

[undone bluff]

you want strafing movement that is not perpendicular to the camera direction?

I'm a little confused

[wraith basin]

That is correct

[undone bluff]

okay

[wraith basin]

So if I'm looking over my characters left shoulder, and I strafe, it'll will be directly left and right relative to the character, not the direction of the camera

[faint pasture]

move and strafe relative to WHAT

so relative to character

so do what I've said to do 3x already

use capsule rotation for your movement vector, not control rotation

then just hook rmb up to enable/disable using control rotation yaw and it'll work

[wraith basin]

I posted a pic where I tried that above, but I'm having the opposite issue. Not sure if I did it right though

[faint pasture]

that should work, now to get the control rotation and capsule orientation thing hooked up right

[ocean crow]

Hey does anyone know why my initialise function is working for the server host (listen server) but not for a joining player? I dont understand why the cast is returning an "Unknown" player character.

[faint pasture]

your 2 states are that you either use control rotation yaw or not. You never orient to movement as far as I can tell.

[faint pasture]

get player controller 0 is gross

[ocean crow]

how do i do it correctly lol

[faint pasture]

what class is this code in?

[ocean crow]

its in a player hud widget

[faint pasture]

why is the widget telling the inventory to initialize?

don't

[ocean crow]

should it be in the player controller?

[faint pasture]

either that or gamemode

something that exists on the server and is network aware, the widget is neither

[undone bluff]

?

[faint pasture]

no

just enable/disable using control rotation for the pawn's orientation

that's it

[undone bluff]

right

[faint pasture]

movement is always relative to pawn orientation
Camera always follows control rotation
Mouse always changes control rotation.
When RMB is down, pawn orientation follows control rotation

when it's not, it just stays at whatever rotation it was last at

you're after WoW style controls right?

[ocean crow]

what would be the difference between the gamemode and the player controller, if I were to initialize it on one of them

[faint pasture]

gamemode exists on server only and is already the thing creating the pawn to begin with

so while it's doing that, it might as well initialize it too

[ocean crow]

so the player controller is essentially instantiated for each connecting player and doesn't exist only on the server?

[faint pasture]

no it does exist on server

refer to the diagram

[chilly plover]

Would anyone know why my decal reflects white when there is no light and shines white. It is a blood decal. How can I stop the reflection of lights or reduce it?

[faint pasture]

[ocean crow]

ty

[faint pasture]

show material

[chilly plover]

This is the master material BP

It ends up looking like this in the dark

[turbid pecan]

@faint pasture last bit of pestering if I may.. This set up for movement right here works beautifully. Although it is not conducive to quick succession movement. Like Clicking W repeatedly will still be the same animation speed and the timeline doesnt do much to speed it up and I suspect this is to do with the do once node?

I tried without it, but this ends up with pretty big drop in collision accuracy and i sometimes phase into walls

[ocean crow]

So this happens in my gamemode when a player joins, how can I get a reference to the widget reference (UI Inventory Ref) from the HUD widget?

[faint pasture]

why you got emissive color?

[faint pasture]

You'd probably want a queue of moves and a timeline that goes through them

or just speed the timeline up

Either way, if you want to avoid the problem if clipping through corners you have to have something that makes the intermediate moves

[chilly plover]

Thanks, removing emissive worked 🙂

[turbid pecan]

I see. Okay I’ll dick around with it some more tomorrow. You’ve been a big help. I’m really grateful for your help.

[faint pasture]

You probably want emissive in your material for glowing liquids but yes, blood usually doesn't glow

if it is glowing, you've had a REALLY bad day

[turbid pecan]

3.5 roentgen - not great, not terrible

https://tenor.com/view/chernobyl-head-shaking-no-nope-gif-14984959

[wraith basin]

That is exactly it, and I tried to figure out what you mentioned regarding using RMB to enable/disable using control rotation yaw, but I don't think I'm doing it right. My assumption was that I'd call the RMB event and store it as a variable, and then turn Control Rotation Yaw on or off based on that, but that's not working. Once again, I'm very new, so I apologize for my ignorance if this is done completely wrong

[faint pasture]

You can just directly set use controller rotation yaw or just directly get the input action value

you have a lot of extra steps

[wraith basin]

So like this?

[faint pasture]

put a print on those and make sure it's responding to clicks the way you want it to

[pastel garnet]

Can anybody help me solve this issue? I am trying to create a drag and drop but it only works when the (Generic button) is disabled and not when enabled. Any more information needed please let me know

[wraith basin]

So it responds to my clicks as expected while stationary, but not while moving, which coincides with my current issue

[faint pasture]

why would moving change that?

you sure you don't have orient rotation to movement turned on?

[ocean crow]

Can anyone help with this?

[faint pasture]

Why does the gamemode care about widgets at all?

are you storing game state in your widgets?

If what you're after is a way for the widget to know that the inventory is initialized, use a repnotify probably

[ocean crow]

No, i just want to open the inventory when a player presses tab. My issue is that I cant get the player controller in the widget blueprint (using get player controller index 0) to return a correct player pawn for a joining player. Works on the host, not anyone who joins.

[faint pasture]

but either way the gamemode doesn't care about your UI at all, it just does its thing. Whatever is storing your inventory data is responsible for letting the UI know it's been updated (or better yet, the UI just binds to a dispatcher on it)

[faint pasture]

delete every get player controller 0 in your project

[ocean crow]

lol

[faint pasture]

for real

Start from the top, what class is spawning your widgets?

usually it's PlayerController or HUD

[wraith basin]

I'm not sure, and it is not. Whenever I'm moving, the print string doesn't appear, and whatever state it was in before the character starts moving is what it gets stuck in until I stop moving. So if I hold the RMB and then start moving, then Controller Rotation Yaw is enabled, but if I don't, then it's the normal controls

[ocean crow]

lets say HUD

[faint pasture]

which is it actually?

[wraith basin]

Here's my current blueprints if it's any help

[faint pasture]

that looks fine

[ocean crow]

player controller

[faint pasture]

so the widget shouldn't have to look very far to find the playercontroller it cares about, it's held by it

[faint pasture]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Widget/GetOwningPlayer/

thats it, thats the playercontroller which owns the widget

[faint pasture]

what is your tick doing right now

[cold lion]

I am trying to follow a simple tutorial and im only about a minute in and this i not working for me

[faint pasture]

show more

[faint pasture]

but a behavior tree component and a behavior tree are not the same thing

[wraith basin]

Nothing, it's currently not being used

[faint pasture]

try:
Tick -> UseControlRotationYaw = IA_RMB

you can just get input axis values whenever you want

you don't need the input axis event

[cold lion]

I have done this before and it worked but am redoing it cause of other issues that happend this is the working one and I can't figure out why

[wraith basin]

Good to know, thank you

[faint pasture]

is BaseSecondEnemy a subclass of BaseEnemy?

[cold lion]

it's a new one

[faint pasture]

your object types for BehaviorTree variable are different

one is a component, one is not

why is it not a subclass though

[cold lion]

I must be blind

it's not a subclass because I am remaking it to fix another issue to see if I missed anything

[ocean crow]

Any idea why this still returns "Unknown" for the cast?

[faint pasture]

Don't rely on the debugger

when are you calling this?

your pawn might not exist yet

[ocean crow]

here in player controller

[faint pasture]

that does not tell me when

show more

[ocean crow]

event begin play*

[faint pasture]

that might be too early

[faint pasture]

also you want to gate by LocallyControlled, you don't want to try set up UI for the serverside playercontroller

[faint pasture]

yeah that's way too early

you just told the server to spawn you a pawn, and now you want to get at it

the server hasn't even got your request yet

welcome to multiplayer

[ocean crow]

yay

I am gating by LocallyControlled correctly there right?

[faint pasture]

yeah that looks fine

[ocean crow]

when should i call it then

[faint pasture]

the controller requesting a pawn is a bit sus

[faint pasture]

When the pawn is there and possession has already happened

do you hvae access to AcknowledgePossession in BP?

[ocean crow]

I have event on possess?

[wraith basin]

I figured out what was wrong. I had implemented the ability to move forward by holding both the left and right mouse buttons simultaneously, and that was getting in the way of your solution. Got rid of that and everything is working as intended, I just need to figure out how to add that functionality back without breaking the camera now

Thank you so much for you help, it's really appreciated

[ocean crow]

Doing this works fine in singleplayer and for the server host, cant even open the inventory on a client

these are the errors

referring to this initialize function, which has an is valid inside:

[chilly plover]

Is it poossible to get a random number between 0.0 and 1.0 to replace the 0.2 value? So this will be random everytime

[cold lion]

Blueprint Runtime Error: "Accessed None trying to read property CharacterMovement". Node: Branch Graph: Handle Enemy State and Calculate Degrees Function: Execute Ubergraph BP Base Enemy Blueprint: BP_BaseEnemy

I keep getting this error yet if I copy and paste my enemy in it functions fine but making a duplicate or child does not work, am I missing something? the rest of the code is just making the 8 way sprites trigger and rotate correctly

[faint pasture]

because OnPossess isn't AcknowledgePossession

[faint pasture]

every what time?

every frame?

every instance?

[chilly plover]

Just randomly in seconds

So when I dragf ther light out they don't all flicker at the same time

[faint pasture]

so per instance

per instance random is the node you want

[chilly plover]

It doesn't let me add it on the material though

[crimson saddle]

Does anyone have good tips for optimizing nested arrays?

In my case I need to iterate through a bunch of actors, check an array of their values, and compare it against another array of values.

I'm not really sure how to optimize this well, since I need to recalculate my values knowing that many of them have changed. So I can't really cache them to save calculations (besides storing the result until next calc like I already do), and if I update as values change then I basically need to calculate the same thing in reverse.

[brazen merlin]

I dont fully understand... working with arrays in parallel is not ideal?

[crimson saddle]

that is the issue, I'm not sure how to avoid the arrays

[brazen merlin]

Well there are structs.....

Data tables....

Like i said, i dont fully understand.. so i can only think of the other data types that can be utilized

[ocean crow]

anyone know why this returns "No Player Controller" for connecting players but not for the host?

[edgy ingot]

OnPosses only run in server

Dont add delay its not even a bandage, u dont know how many second u have to wait since that depend on ping

[crimson saddle]

I can try to clarify more.
I am running calculations that need to compare multiple arrays from multiple actors a couple of which are maps of arrays, which naturally requires lots of nested loops.
So like Actor>Map of arrays>Array compare against Array and do it for everything in the map

I'm trying to figure out how to optimize that process a bit more because obviously my operations will grow exponentially.

[edgy ingot]

Convert the 0.2 to parametre. Then you can dynamically set the value in bp using set scalar valhe node. look for infos on dynamic material instance

[edgy ingot]

Heard looping thru array is slow in blueprint, if your calculating a lot of stuff then you are already hitting the wall in bp.

It really depends on the size of the array. A few hundreds probably wont matter imo

If you want speed then do it in cpp

[crimson saddle]

Ah I was afraid of that
I'm not very comfortable with cpp and vs sucks for performance

[remote meteor]

vs2022 doesnt suck tbh 😅

[silk cosmos]

This is going to fire for every user. Either add the input mapping in the player controllers begin play instead or use is locally controlled -> true before the cast

[ocean crow]

Thanks yeah this makes more sense

[long torrent]

Hey yall I was wondering if anyone had run into this before, basically I am using a waterfall fx blueprint to simulate the wake coming out the back of this ship. Its just a mesh along a spline, however the meshes keep despawning depending on where I look. I don't have World Partition enabled or mesh streaming or anything. I am not sure why this is happening.

[silk cosmos]

Just a guess but it might be an issue with your meshes object bounds since it seems to be related to your cameras transform. It could either be in a weird spot/too small. You should be able to increase the bounds scale somewhere

[long torrent]

Oh yes! I think that did it! Thank you 🙂

[boreal crypt]

Is there a way to get a variable from the level blueprint from an actor?

I see getLevel as a node, but from that I can't get any of the level blueprint variables.

Nm, gamestate makes more sense to hold these variables

[edgy ingot]

You cant in bp. Dont use level bp for gameplay stuff

[crimson saddle]

Maybe it's time to finally learn then
I've just never experienced good performance from vs, nor have i seen it markup UE cpp properly

[remote meteor]

back then in vs2019 yeah it sucked

[queen heron]

I'm tryna create a data asset with the information I'm setting through the utility widget

the data asset is succesfully created yeah, but it comes up empty right now

[brisk rain]

Hello! I'm trying to figure out how I can make a global leaderboard for the 10 top scores. Do I need to do it manually every update, or can I connect to a database where I can send (or even put manually) and retrieve scores?

[edgy ingot]

Your call?

Can just retreieve the data when you open the widget or refresh it as often as you like depending on your need

[remote meteor]

open widget, asynchronously retrieve

usually

if you want immediate then maybe a periodic background query, then whenever widget shows up, refresh to latest local copy

[brisk rain]

yeah I figured that out, but how do I retrieve the information?

[edgy ingot]

Where do you want to store the data base?

And how

[brisk rain]

I dont know... anywhere

any reccomendations ig?

[edgy ingot]

I dont tap into this sort of thing but if u have a website u can prob use mysql

Or you can have it in a txt file somewhere on the net

I can only give crappy ideas

[brisk rain]

I found a tutorial for mysql

[brisk rain]

its alr lol

[edgy ingot]

U will still need a server tho

There is already plugin for leaderboard afaik

If i have to do something like this, i would just use api and make http request

[shy gorge]

anyone know a fix to a problem when I create blueprint and all added default data disappear when I save the bp?

[cyan jetty]

I want to create a character bluprint that I can place as often as I want. If you left click on it the camera should switch to the new character (works). However, you cannot control the camera but continue to control the one of the first character. All characters have the same BP

[lunar sleet]

Use Possess

[cyan jetty]

whats that?

[ocean crow]

ok i still cant figure this out i dont understand, why does this print string return null for joining players but not for the host of the session? this snippet is run on event begin play, if I run it on event possess its null always, idk surely I am missing smth obvious?

[dark drum]

If I remember correctly, possession isn't completed until the following tick so could be related. If you add a delay until next tick does it still return null?

[dark drum]

You need to tell the controller to possess the new pawn/character otherwise it won't receive inputs from the controller.

All you're doing is changing the camera it uses to view the world from.

[marble marlin]

Can I export blueprints in some more functional way that just screenshotting them? I would like to make myself a catalogue that can ideally be rendered somehow in Obsidian. Thank You.

[dark drum]

It's hard to say without knowing more about what the end goal is. Saying you need to compare arrays isn't much to go on.

Depending on the values/data you're comparing, sometimes using 'sets' can be more efficient. Especially if you just need to know if a set contains a list of values and similar operations.

[dark drum]

What's obsidian?

[marble marlin]

SOrry, note taking app, it can do markdown, bit like oneNote, Notion, etc.

[steady night]

Fuc¤#"%¤ is this dumb ass shit ?

[queen heron]

have you tried disconnecting the connection from the add input and the float variable output and connect back?

[steady night]

i just delted all and redid

worked...

just UE being stupuid

[queen heron]

hmm

[edgy ingot]

On posses only run on server machine

If you need to run something on client machine use acknowledge possession

[edgy ingot]

https://blueprintue.com/

Dont know anything about the software you use but there is blueprint paste bin which can be embeeded afaik. Never used it my self

[ocean crow]

Doesnt work unfortunately but delaying it by 1.5 seconds does

im testing at like 500ping so 1.5 seconds is probably overkill, but eh it works

[ocean crow]

In blueprints? I dont see a node that says event on acknowledge possession

[edgy ingot]

Not sure if its available in bp but imo it should be exposed

Using delay is not a bandaid for multiplayer

U gotta set things in the right places

[dark drum]

If it's longer than next tick, it'll be waiting for it to replicate. As cold said you'd definitely need to look at a different way to handle it.

[ocean crow]

Oh so I can't be certain that if a player has less than 500 ping it will always work?

[ocean crow]

How can i expose it

[remote meteor]

if you need the controlled pawn in the player controller, you can just use Possessed event

[heavy lynx]

Hello everyone, could anyone help me with some apparently simple math ? I have this function that is executed every tick to find an increment to set an actor location along a spline using some fake physics, but I can't find how to make it frame independent, I tried using the delta seconds but it scales unproportionally... By that I mean at high frame rates, the train updates faster and the math is more accurate so it slows down a lot more due to friction, while at low frame rates the train also updates rather fast (I haven't measured how much faster/slower than at high framerates) but slows down less making it able to traverse more distance... I would need help fixing the function so that the math stays independent of FPS

The function : https://blueprintue.com/blueprint/fvoh_7lo/

(the value "Increment" is used every tick to find the location at distance along spline (Distance=LastDistance+Increment))

[frosty heron]

What's the goal? You want to set inventory component both on the server machine and client machine?

[cosmic kiln]

gentlemen i'm in a bit of a predicament

recently i came to seek help to see how i could make the weapon model independent of the camera's FOV

and i've been informed that you can use a world offset value in materials

now i found out how to do it and it works HOWEVER there is one problem

the gun blueprints themselves also acts as pick ups, which means that the offset's there even when the gun's not picked up

which gives a weird effect of the gun moving around

how can i make the offset apply only when the gun is equipped and not before then? do i need to overhaul my pick up system??????

should i ask this in the #materials channel??

[ocean crow]

yes, but im doing it on the player controller so ideally just for the respective player controller. This works fine on the server host and in singleplayer, however when a client joins the server it returns an invalid controller as it is run on event begin play and hence was called before the controller was assigned. Event on possessed doesnt help either for some reason, it actually doesnt work on the client or the server host or in single player.

I also dont see why that delay wouldn't be a suitable fix? Surely if I'm simulating everything with 500ping in the config file then I'm looking at a worst case scenario always, and so unless someone somehow connects to a host with more than 500 ping, the 1.5 second delay node would solve the problem wouldn't it?

[frosty heron]

I don't know how others do it but I have nothing on my event begin play on both the character and controller

I set my mapping input on posses for the server

And onacknowledgepossession for client

Did my cosmetic logic there too

Tested with high ping , no problem

[ocean crow]

Is there no way to access the onacknowledgepossession outside of cpp?

[frosty heron]

I just pack up my pc so I can't open the editor

Also I'm just another newbie in mp. Your best bet is to ask in #multiplayer

Anyway the problem right now is you don't have a valid controller?

I mean on posses shouldn't even run in client. R u sure that accesses none happend for the specific print string?

[ocean crow]

yeah it does, im gonna leave it on a delay for now and work on it later, ik everyone has said it's not a working solution but it allows me to test other parts of my game in multiplayer so il get back to it when i need to

thanks for your help though much appreciated

[cosmic kiln]

got no clue

[frosty heron]

K well when I got my pc set up again, I will play around and let you know

[ocean crow]

ty

[frosty heron]

Can u print string the controller too, I have a feeling that u might have valid controller but it doesn't have a valid pawn yet.

Just pure guessing

[stuck sentinel]

I have two problems here, the material is weird and some pieces are like half visible causing these

[frosty heron]

That's a lot of material id for simple object

[light garnet]

Do you have to replicate the construction script??

[frosty heron]

Wdym by that

[light garnet]

Construction script in character blueprint

[frosty heron]

It might be normal problem

[light garnet]

If i implement something there then it works on multiplayer?

[frosty heron]

You are looking at the rear side

[light garnet]

Or i have to replicate?

[stuck sentinel]

i made each one then i grouped them is there a better way to do it?

its all one material

[frosty heron]

I mean don't see how replication have anything to do with construction script

It will simply run on every machine

[light garnet]

I have implemented an attached gun to the component. So it will work on server and client?

[frosty heron]

U can just use one UV and a few material Id. Anyway I think you are looking at the backpack, that's why it's "invisible"

[stuck sentinel]

backpack?

[frosty heron]

Backface*

[stuck sentinel]

how do i fix that

[frosty heron]

U gotta flip the normal on that face that has problem

In your 3d software

[cosmic kiln]

ok i have a much bigger issue now

my character movement legit just nuked itself randomly

completely blank

looks like i'll have to load a backup, fuck my life

[frosty heron]

Haven't we met b4

[light garnet]

I don't remember

Do you know me?

[frosty heron]

I think I used to pay you to do stuff

[dark drum]

Select all faces and press Ctrl + N. Assuming good topology, it should fix it for you and show all blue.

[fluid lagoon]

For some reason my gamemode on begin play is showing an accessed non error for my Sun Variable, the sun var is a directional light contained within the player

And also even though there are no DLs in the level, no light appears

If anyone knew the best course of action Id be greatful!

The specific error Im getting also

[stuck sentinel]

WHAT DO I PUT HERE

[frosty heron]

A reference to w.e you are casting

Casting is just a type check

[undone bluff]

idk what the heck is a Net

I assume a random actor not using naming conventions

[frosty heron]

Ye u got a bug

[undone bluff]

you need to input a reference to the instance you want to cast to

[frosty heron]

That thing happend in 5.3 qfaik

[stuck sentinel]

A FOOTBALL NET

[frosty heron]

@cosmic kiln if you have source control, maybe u want to roll back. Otherwise u r fucked I think

[stuck sentinel]

what

[stuck sentinel]

i want to get the score variable from the net blueprint

[frosty heron]

Then get the net

[undone bluff]

yea, so you need to tell it which net to cast to

net itself is just a class

[stuck sentinel]

how do i do that

[undone bluff]

in the game it is instantiated, i.e. an instance of the class net. you need to get a reference to it somehow

[frosty heron]

Your game you decide. You need to pick some net that exist in the world then feed it into the cast

[undone bluff]

and there's a lot of approaches

[stuck sentinel]

this one

[undone bluff]

hell, casting should be your last resort, it creates a hard reference/dependency

[stuck sentinel]

is there another casting method

to get a variable from one blueprint to another

[frosty heron]

Casting is just a type check. It is not a method to "get one blueprint to another"

[stuck sentinel]

then what do i do

[frosty heron]

Only in bp and it can't be dodged. Ppl try to dodge it with interface but ends up with hard ref anyway

[frosty heron]

R u spawning net at run time or are u gonna place it in the level?

Also put prefix like bp_net

It's hard to read

[stuck sentinel]

place in the level

[frosty heron]

Make an actor blueprint right now, call it game manager

[stuck sentinel]

done

[frosty heron]

In game manager create a variable of net

Make it an object ref

[stuck sentinel]

variable of net?

[frosty heron]

Yes

[stuck sentinel]

how

[frosty heron]

Create variable, type net. Then select object ref

[stuck sentinel]

done

[frosty heron]

Make it instance editable and expose on spawn

Select the variable and tick on the boxes I mentioned

[stuck sentinel]

done

[undone bluff]

well that cannot be true, I have an entire inventory, interaction and electricity system while keeping dependencies in check, at worst I'm rarely casting to class pawn or character

[frosty heron]

Now drop game manager to the world

[stuck sentinel]

done

[undone bluff]

I love the eyedropper feature so much

[frosty heron]

You should always cast to base class when possible that's right but saying casting is harmful, I have to disagree because you can't really dodge that making a game.

It's just the price that one have to pay for using blueprint only

So if the project is bp only, cast anyway no avoiding it but you can always use soft ref to load the heavy stuff like material, mesh etc

[stuck sentinel]

then what

[undone bluff]

probably make it an array

since I assume there will be 2 nets?

[frosty heron]

Click the game manager u drop to the world then look for the net variable. Select the eye dropper and pick the net in your world

[frosty heron]

Ye I dunnoe what the game is about

Just gonna give example

This feels like private tuition already

[stuck sentinel]

done

❤️

then what

[undone bluff]

that's your reference

[frosty heron]

Now go to the bo where u trying to cast again

Bp*

[stuck sentinel]

yeah

[frosty heron]

Get actor of class select bp mamager

From the return value get net

Now that's your reference

It points to the net u selected

[stuck sentinel]

you mean game manager

there

[frosty heron]

Well there u go

Don't even need to cast

[stuck sentinel]

okay but now how do i get the score variable

from net

[frosty heron]

That's Ur net, do w.e u please with it

From the blue pin of net drag and type get score or w.e variable it has

[stuck sentinel]

but i want the variable here

[frosty heron]

That's Ur damn widget

And not the bp u trying to cast in the first place

Widget job is just to read

[stuck sentinel]

yeah

so i want to return the score variable so it displays my score each goal i score

[undone bluff]

generally whatever creates the widget should keep a reference to it and manage it

which should probably be the game manager you made

are you displaying the widget in screen space or world space?

[stuck sentinel]

screen i guess

[undone bluff]

that return value on the create widget node

promote that to a variable

before adding to viewport

[stuck sentinel]

ok then

[undone bluff]

get actor of class

[stuck sentinel]

this right

[undone bluff]

this

[undone bluff]

no the return value

that's the reference

[stuck sentinel]

okay

[undone bluff]

yea you need to set that

[stuck sentinel]

ok done

[undone bluff]

call it score widget reference or something

[stuck sentinel]

ok then

[undone bluff]

then you get a reference to the game manager, cast to it and hand it the reference you just made for your widget

[stuck sentinel]

after add to viewport?

[undone bluff]

yes

just copy and paste the variable you made to hold the reference for the widget

into the manager

[stuck sentinel]

ok then

[undone bluff]

and then you cast to it to set it too to the same value

[undone bluff]

return value > cast to game manager

[stuck sentinel]

ok then

[undone bluff]

as game manager set the widget reference to the same value as the one in the character blueprint

you need to copy the variable over to it first

[stuck sentinel]

the score variable

?

[undone bluff]

score widget reference

[stuck sentinel]

like this?

[dark drum]

If you're using the get all actors of class, I feel like using the game manger just to get a ref to to net is a little redundant.

[undone bluff]

no you are setting the one in the character blueprint again

[stuck sentinel]

do i go over to widget blueprint

[undone bluff]

use the "as game manager" pin

[stuck sentinel]

alright

[undone bluff]

the game manager will hopefully be keeping track of the score and setting the widget instead of the player

as well as any other logic

this whole setup is scuffed but of well

it's probably fine for the type of game

[stuck sentinel]

what do i link to it

[undone bluff]

you set the reference in the game manager

just like you did in the player character initially

[stuck sentinel]

in the gamemanager blueprint?

[undone bluff]

yes

it should have an identical variable to hold a reference

[dark drum]

An actor component on the game state to manage important actors and having the net register itself on begin play would be better.

The game state is much easier to access removing the need for get all actors of class which at this point could just be used to get the net.

[undone bluff]

you're 100% right that is what the game state is for

[stuck sentinel]

what now

[undone bluff]

I did not suggest the usage of a manager blueprint

what we're doing is instead a good approach if this was just a minigame in the scope of a bigger game

which is probably not the case

[undone bluff]

score widget reference, copy that variable from the player and paste it in there

[dark drum]

The best thing to do is spend some time learning about BP communication before you continue. If you don't understand it you're going to run into many issues.

The premise of getting a reference is very basic stuff.

[stuck sentinel]

done

[stuck sentinel]

i did but i forgot it

[undone bluff]

as game manager, set the reference in the game manager to be the same as your player character

using the cast

[stuck sentinel]

where is the as game manager

[undone bluff]

in your player character

[stuck sentinel]

mhm

[undone bluff]

yóu cast to it

[stuck sentinel]

get or set

[undone bluff]

set

[dark drum]

Then go over it again lol. There's a lot of hand holding with micro steps which I feel you don't really understand.

[stuck sentinel]

ok then

[undone bluff]

seriously you need to spend a few days getting your basics down, following step by step instructions will not help you much

[stuck sentinel]

reccomend me a course

[undone bluff]

unreal courses are pretty much all horrible

[stuck sentinel]

you mean from the unreal website

thats the one i did

[undone bluff]

ah the unreal website is fine

[stuck sentinel]

ok what course do i do

[undone bluff]

i thought you meant like udemy courses

I'm not sure I never watched any of them, they did not exist when I started

[stuck sentinel]

how did u learn blueprint communication then

[dark drum]

UE documentation. 🙂

[stuck sentinel]

wdym

what is ue documentation

[dark drum]

https://docs.unrealengine.com/5.3/en-US/

[stuck sentinel]

should i learn from there

[undone bluff]

https://dev.epicgames.com/community/learning/courses/LWv/unreal-engine-blueprint-communication/ypKl/unreal-engine-blueprint-communication-overview

this looks fine

[stuck sentinel]

i did this one

[undone bluff]

probably do it again haha

[stuck sentinel]

oh btw

you know poppy playtime the game

was it made using blueprint or c++

[dark drum]

https://docs.unrealengine.com/5.0/en-US/blueprint-communication-usage-in-unreal-engine/

[stuck sentinel]

should i do this or a visual course

[undone bluff]

the documentation pretty much covers the same stuff

[stuck sentinel]

which one is better for my 47 iq

[undone bluff]

I'd personally watch the course and then read documentation, reinforcement learning is king

wait that's not what reinforcement learning means

[stuck sentinel]

how does the documentation work

do they give examples or tell yo what it does or what

[undone bluff]

it explains the different approaches to communication and its advantages and disadvantages

you can just look at it yourself it's not long

imo much better and faster than any course could be but people learn differently

do what works for you

[frosty heron]

You can watch Matthew blueprint communication video

It's less than 15 mins

[stuck sentinel]

can you send

[frosty heron]

I'm picking up rn. Youtube and type the title

[stuck sentinel]

and guys you know poppy playtime the game
was it made using blueprint or c++

[frosty heron]

Packing

[undone bluff]

nothing in that game that couldn't be done in blueprints

[stuck sentinel]

what aside from multiplayer cant be done in blueprint

[undone bluff]

it's not so much about what can't be done

and multiplayer can definitely be done in blueprint

it's often a matter of things being a pain to do or running very slow in blueprint

there's some engine functionality that just isn't exposed to blueprints

[stuck sentinel]

could i do a full blueprint game with the stuff needed in c++ as bought assets

[undone bluff]

maybe

[dark drum]

Very slow is a misconception. In most cases performance is negligible unless you actually need multi threading.

[undone bluff]

there's an inherent cost per node

it is negligible generally

but sometimes it is not

any kind of heavy checks, calculations etc. will be much much slower

[dark drum]

For heavy calculations you should use the math node.

[undone bluff]

the operations themselves not

yea, that is just C++ after all

I was thinking of, imagine you need A* pathfinding

any kind of recursive/iterative algorithms are hell

[dark drum]

Then I would use UE's built in path finding system which I'm pretty sure is A*.

I can remember reading a post a few years ago of someone implementing their own A* in BP and it worked fine.

[frosty heron]

Blueprint multiplayer is very limited

Don't take my word for it ask in #multiplayer

[undone bluff]

last time I checked it is heavily limited to a generated horizontal navmesh (though it can be generated at runtime)

doesn't work for many games

[frosty heron]

If the game doesn't need to care about ping. Eg chess, then I wouldn't mind using bp only

[undone bluff]

it's all fun and games until you try to change the movement speed

though the replication the movement component does for you by default is super impressive

[frosty heron]

Expanding cmc is for intermediate. Luckily someone covered it... otherwise I wouldn't be able to implement it on my own

And that's where bp hit the wall too

U can't expand cmc in bp

Cpp only since you have to change the byte flag

I think changing walk speed is fine, problem is for something like sprinting, crouching etc

[undone bluff]

yea, change in runtime, I meant

[frosty heron]

Lots of fake tutorial in youtube doing sprinting in multiplayer with bp only

[dark drum]

What do they do?

[undone bluff]

realistically, I need to either make my own movement component or really make sure I understand the existing one and it's quite intimidating

[frosty heron]

They implement their own bool for sprinting

Then show that it "works"

But the truth is add a little lag like 5 ms. Surprise surprise game broken

Player get rubber banded every frame

[undone bluff]

hate having code in my game I do not fully understand, some of my approaches feel super hacky

[frosty heron]

Someone did. Took him a year. The very same person that guide on how to implement sprint in cmc for multiplayer

Mover 2.0 coming in 5.4

Maybe that can be the saviour

[undone bluff]

thing is just way too big

wish it was divided up nicely

[frosty heron]

Cmc is made with capsule collision in mind too

So if u need a custom collision then rip

There is general movement component in market place that address the issue. I think it cost 350 dollars at least

[undone bluff]

I'd pay for it but then I'd have to understand how that works and that doesn't feel much better

[cosmic kiln]

i don't but i had a backup it's alr

[undone bluff]

I just don't want to have an opaque black box that handles the movement in my game 😔

[frosty heron]

Make sure the detail panel is there

[undone bluff]

what is the parent class of yours?

reparenting tends to fix most corruption issues

if it's child of a child of character for example

reparent to character and then back

[fluid lagoon]

So to my understanding, the player start needs to be half way into the ground for VRPawn to spawn correctly, well my player start wont actually spawn my VRPawn and infact sets me to spectator mode and spawns me at the world origin, I have no idea why and Im at a complete loss

[frosty heron]

Read the warning

If Ur player start collide with something, it's going to fall back to doing something else depending on the spawn rule

Maybe there is option to spawn anyway while ignoring collision.

Select your player start and look around for the spawn rule

[fluid lagoon]

Ok Im an idiot I fixed it, so the player start has to be half way into the ground due to tracking capabilities, however, my VRPawn had static meshes with collisions enabled, so it was never going to spawn, jesus I was about to start ripping my hair out big time

Thank you @frosty heron for responding to my cry for help tho, if my brain hadnt have started working you would have been my saving grace

[dry sleet]

Doesn't the math node just construct a graph of simple math operator nodes?

IIRC you can open it to reveal a collapsed auto-gen graph

[undone bluff]

yea it does, good call

https://docs.unrealengine.com/5.3/en-US/math-expression-node-in-unreal-engine/

[remote meteor]

and crash prone in 5.3

[dark drum]

From my understanding, that's just a visual representation. It's closer to c++ performance when handling complex equations.

It was many years ago but epic mentioned it in one of their live streams.

[undone bluff]

apparently they were changed to the collapsed graph setup later on

might be a similar situation to blueprint nativization

i'd love to profile it but a lil busy atm

[cosmic kiln]

it is

[main lake]

General question : If I make a project template with alot of stuff in it (blueprint actors, gamemodes, etc...) to sell it on the marketplace, is there a way for the buyer to "reset" the object to the state of when he bought my template in case he made some changes ?

By that imagine, I created a template and inside the BP_Character, I have an actor component handling the health for the player, and I wrote a logic to clamp the health to not go below 0, not going above MaxHealth, a method to catch damage, etc... And the buyer went into that component and start messing with the stuff I made to do some tests or make it fit his needs. But the buyer messed up the things and want to get that component back to its original state, with the default value I set, the logic I wrote, etc... without having to create a new project with my template. Is that possible ?

[dark drum]

Interesting, if that's the case I definitely missed the change. I have used the math expression node before and found a slight improvement in performance when profiled. It would be nice to know if this is still the case. Of course if they've made performance improvements in other places it might have become redundant in that regard.

[undone bluff]

when you add the component to a character and change the values you're only editing the instance

or rather how it is instantiated I guess

the default values will be the ones that are defined in the component itself

[main lake]

But what if he starts touching the actor component itself created outside of the character ?

[main lake]

yeah I'm more talking about if he changed that part

[dark drum]

This is where creating a child comes in handy if they need to do more that change the default vars.

[remote meteor]

to revert, the buyer will have to import the asset again

[undone bluff]

I think you are worrying over nothing

[remote meteor]

asset bought from marketplace is just copying to the project

[main lake]

It's just a genral question I have (I'm not doing a project like that currently 😛 ) but that question popped into my mind

[undone bluff]

this is entirely the buyer's responsibility, all you should do is provide an artist friendly setup with inheritance

if they mess with the core functionality that's up to them

[dark drum]

Does anyone know how to only show actors in the level outliner that are of a specific actors (or child of)

[undone bluff]

I have never used this but maybe?

also lol stacked outliners

[dark drum]

Yea, I've had a play but can't do it. (not sure if it works) I tried the same thing that works in the content browser but it doesn't show anything.

[main lake]

If you created a new filter and type in the "Filter String" the keyword like a keyword in the name of your class, it should work properly

Like for instance

[dark drum]

That's still only based on the actual name as opposed to the class.. So if I have an item base class called BP_Item but create a child that's call BP_Rock, the rock wouldn't show.

[main lake]

I see. But maybe then you can change your naming convention, to always have the name of the base class first then the name of the child class. Like instance of being BP_Rock, it could be Item_Rock ?

[dark drum]

I could but then I'd also have to make sure other things don't include that section.

[main lake]

what do you mean ?
